Resolving to a chord just means that the music sounds "complete" when it hits that chord. In other words, it wouldn't sound weird if the song ended right there.

Resolving to a chord just means that the music sounds "complete" when it hits that chord. In other words, it wouldn't sound weird if the song ended right there. For example, if you hear "Happy Birthday" played in C, the final chord is C major, and the song sounds done. If you heard it with the final chord changed to something else, it would sound like it was leading somewhere, and you'd expect another verse or a bridge or something to follow.
